To @21mmaaa/aaa,...

Be itiknown that I,J0HN.M. PERnINs, of the` city,county,"and\gState ofNewl York,

" have invented a new and Improved Mode of AttachingVI-Iubs to Axles;and I do hereby `declare `that thefollowing .is a full, clear, and exactdescription of` the same,freference j `being had tothe annexed drawings,making' a part ofthis specification, in which-` Figure 1, istawlongitudinal section cfa 4hub attached to an axlelaccording to my imjlproved mode. Fig. "2, isla back view of the chulo. Fig. 3, is a` viewlofthe inner side of the cap. Fig. l, is a: section of the cap andlanches attached to the `back end" of the hub,

(fr) showingtheplane ofsection.l Similar lettersof reference indicatecorresponding parts in the several gures.

The nature of my invention consists in the peculiar means*` employed forVsecuring the hub tojthe axle.`

A, represents` the hub of usual construce tion and havingits front; endcovered peri j manently 4bya plate' B, and a band C, aty `tached to the`backend of itsperiphery.

" I D,representsthearm'ofthe axle E, and

F, represents `a circular cap which isdiitted i loosely onthearin 1),;adjoining the shouli i der` (a) of theaxle, saidfcap being secured inproper place uponthearm by a collar G, as

i i 'Fo the back end of the hub A,'there is at. tached four,"1nore`orless, segment projections (o) the j outer `edges of which, vare creasedorgrooved as shown in Fig. 1, and H also inclined orbeveledlongitudinally as H "shown` in Figs., 2 `and .4. 3 Thereis also iniserted a pin I-I, in the `back end of the hub the yinner endofiwhichbears against a spi- `The innerisurface of thel cap is providedat its edge with foar lips (dthe number of lipscorresponding with thenumber `ot projections these `lips project `inward or towardthe centerof the plate F,

' cap F, there is made a hole (e) to receive the pin H. M i

To attach the hub to the axle the cap E, is placed against the back endof the hub A,

`the lips (d) being between the projections (o) see Fig. 4. The cap isthen turned from left to right and the lips pass over theouter edges ofthe projections (b) and the pin H,

passes into the hole (e), see red lines Fig. 4. The pinH, prevents thelips (UZ) from passing off the projections (b) when thevehicle ismovedrbackward.

`To detach the hub fromthe axle, the pin II,"'s Jforced back free Jfromthe cap F, by meansof 1a key, shown in redFig. 1.

The above invention is extremely simple,

eiiicient, and economical to manufacture,

and the wheel may be readily attached to and detached from the axle.

l What I claim as new and desire to secure by Letters Patent, is, i

Attaching hubs to axles by having segment projections (Z1) attached tothe back end of the hub, and lips on the inner surface of a cap F, whichis placed loosely on the arm lof the axle, said lips being litted overthe projections by turning the cap, and prevented from moving otl of theprojections upon the backward movement of the wheelor" vehicle by thepin I-I, `as herein shown and described.`
